Hi all, i have created a web application with three classes in it App_Code folder.When i run the pjt in local system everything was working.but after hosting the site it give erroe "Object reference not set to an instance of an object." where it encounter a line having a call to the functions in the class Suppose A is my class in App_Code I have declared the objt of it in a .aspx page as A objA=new A(); objA.Function(); What is wrong with this.I got a solution saying thatfor that "U have to include namespace of APP_code Class File into ur webpage .cs file".How can i do it? :^) :confused: Thanks in advance.

Are you using any name space in Class files ? Are you getting exception while creating a new object i.e

A objA=new A();

OR on Method call

objA.Function();

?

Hi, If your Class file in App_code contains namespace you have to import it in your .cs file. If your code behind is vb then use "import" or c# means use "using" to import your namespace.
